GE Fanuc UR8HH – Universal Relay Module with 8 Poles, High-Hold, High Current

In stock

Product Introduction:
The UR8HH is a heavy-duty universal relay module designed for the most demanding industrial applications. The “UR” indicates Universal Relay, “8” specifies eight relay poles, the first “H” stands for High-Hold (the relay maintains contact closure under high inrush and vibration), and the second “H” stands for High Current (10 Amps per pole). This module combines the highest current rating with the strongest magnetic latch mechanism in the GE Fanuc relay family. It is designed for applications where relays must switch large motors, heavy solenoids, or other loads with high inrush currents, and where the relay must never drop out due to vibration or power fluctuations.

Technical Specifications:
Board Type: Universal Relay Output Module (UR)
Pole Count: 8 independent relay poles
Coil Configuration: Common return (shared return for all 8 coils)
Current Rating: 10 Amps continuous per pole at 250V AC (High Current)
Hold Rating: Maintains closure at 150 percent of rated current (High Hold)
Voltage Rating: 250V AC, 125V DC, 30V DC
Coil Voltage: 24V DC, 48V DC, 120V DC (common return)
Contact Type: Heavy-duty silver alloy with gold plating and reinforced armature
Response Time: 10ms energize, 5ms de-energize
Mechanical Life: 15 million operations (higher than standard due to reinforced design)
Electrical Life: 750,000 operations at full load
Isolation: 500V RMS channel-to-channel
LED Indicators: 8 green coil LEDs, 8 red contact LEDs
Power Consumption: Approximately 14 Watts per module (all coils energized)
Form Factor: 3U Eurocard
Operating Temperature: 0 to 60 degrees Celsius

Functional Features:
High-Hold Magnetic Latch: Reinforced armature and stronger coil magnetic field ensure the relay never drops out under high inrush or vibration.
Eight High-Current Poles: Switches eight 10-Amp loads from a single module, ideal for large motor control centers.
Gold-Plated Heavy Contacts: Thicker contacts with gold plating handle high inrush currents without welding.
Reinforced Mechanical Design: Stronger spring mechanisms and sturdier armatures withstand continuous vibration.
Common Return Wiring: Shared return simplifies wiring for large banks of eight relays.
Extended Electrical Life: 750,000 operations at full load, 50 percent longer than standard UR modules.
